Tires rarely blow out due to over pressure. All vehicle tires are designed to operate well above the maximum cold pressure shown on the sidewall. The far more common tire failure cause is under inflation.
This is also my understanding...however, the notion of what "cold pressure" is has been a source of interest. If you live in an area where the temperature varies wildly from day to day (like 30 degrees, or more), check your tire air pressure the day before the temperature is expected to drop those 30, or more, degrees, and then check again the next day after the temperature has dropped. I have seen a 10 psi drop under those circumstances...so, what is the correct "cold temp" reading?
